Scaffolding in Health Sciences Education Programmes: An Integrative Review

Learning pathways composed of core subjects with features of reducing cognitive load have better learning outcomes

BACKGROUND

Changing the course duration or timing of subjects in learning pathways would influence medical students' learning outcomes. Curriculum designers need to consider the strategy of reducing cognitive load and evaluate it continuously. Our institution underwent gradual curricular changes characterized by reducing cognitive load since 2000. Therefore, we wanted to explore the impact of this strategy on our previous cohorts.

METHODS

This cohort study explored learning pathways across academic years of more than a decade since 2000. Eight hundred eighty-two medical students between 2006 and 2012 were included eventually. Learning outcomes included an average and individual scores of subjects in different stages. Core subjects were identified as those where changes in duration or timing would influence learning outcomes and constitute different learning pathways. We examined whether the promising learning pathway defined as the pathway with the most features of reducing cognitive load has higher learning outcomes than other learning pathways in the exploring dataset. The relationship between features and learning outcomes was validated by learning pathways selected in the remaining dataset.

RESULTS

We found nine core subjects, constituting four different learning pathways. Two features of extended course duration and increased proximity between core subjects of basic science and clinical medicine were identified in the promising learning pathway 2012, which also had the highest learning outcomes. Other pathways had some of the features, and pathway 2006 without such features had the lowest learning outcomes. The relationship between higher learning outcomes and cognitive load-reducing features was validated by comparing learning outcomes in two pathways with and without similar features of the promising learning pathway.

CONCLUSION

An approach to finding a promising learning pathway facilitating students' learning outcomes was validated. Curricular designers may implement similar design to explore the promising learning pathway while considering potential confounding factors, including students, medical educators, and learning design of the course.

Stakeholders' priorities in the development of evidence-based practice competencies in rehabilitation students: a nominal group technique study

PURPOSE

Clinically integrated teaching (CIT) is an effective approach for promoting evidence-based practice (EBP) competencies among medical students. Challenges towards the implementation of CIT in rehabilitation curricula include educators' different conceptualizations of EBP, the perceived complexity of EBP and the boundaries between the academic and the clinical setting. This study aimed to identify tailored strategies to implement in rehabilitation programs and their affiliated clinical sites to support the development of EBP competencies among students in occupational therapy (OT), physical therapy (PT) and speech-language pathology (S-LP).

MATERIALS AND METHODS

Nominal group technique (NGT) with stakeholders from three rehabilitation programs in Canada, offering the professional master's in OT and PT (n = 35 participants) and in S-LP (n = 8).

RESULTS

The top two strategies identified in the OT/PT NGT were: 1) Developing a flexible definition of EBP that recognizes its complexity; 2) Providing clinicians with more access to the teaching content by pairing faculty with preceptors. The top two strategies identified in the S-LP NGT were: 1) Providing students with opportunities for decision-making with experienced clinicians; 2) Increasing interactions between faculty and preceptors using formal group meetings.

CONCLUSION

Findings laid foundations for future integrated knowledge translation projects to collaboratively implement, and test identified strategies.

Usability of Standards for Scaffolding in a Health Sciences Programme: A feasibility Study

BACKGROUND

Standards contribute to comprehensive and programmatic implementation of educational strategies, such as scaffolding. Although the development of educational standards follows a rigorous consensus approach, they are socially constructed and could result in varied interpretations by users. Reports of varied implementation of standards in health professions education underscore the need to test the developed standards for scaffolding in health sciences programmes. Usability entails determining whether a product like standards works as intended under the expected conditions and contexts. This study aimed to describe the usability of standards for scaffolding in a health sciences programme through a pilot study.

METHODS

A multi-method design employing user and expert-based usability evaluation techniques sought to describe the usability of the standards for scaffolding in a three-year pre-registration nursing programme. The user sample of nurse educators drawn from the programme, conducted a self-assessment on scaffolding practices in the programme using a developed standards checklist. For the expert sample, three-panel members with an understanding of the discipline and programme context were purposively sampled. These panelists studied the users' self-assessment reports before completing an author-generated heuristics checklist to support or refute any of the standards. Descriptive statistics, comparative and content analysis were applied to analyse data from users' interviews and expert's completed heuristics checklist, determining the standards' usability, and identifying the usability flaws or strengths.

RESULTS

The users had three or more years of teaching experience in the competency-based curriculum for nursing. The experts shared an average of 16 years of experience in teaching in higher education, and seven years of experience in quality assurance and programme accreditation. The four standards had a usability score of above average (68%). Seven usability strengths and four usability flaws were identified. Usability flaws related to misinterpretation of some criteria statements and terminologies, multiple meanings, and users' challenges in generating evidence for some criteria.

CONCLUSIONS

The pilot study revealed the context-based 'truth' regarding the fidelity of a health sciences programme evaluation on scaffolding, as well as identifying the ideal contextual conditions in which the standards for scaffolding health sciences programmes would work best. The identified usability flaws highlighted the need for further revisions of the standards. Future research on the feasibility of the standards in other health sciences programmes and contexts is recommended.

Twelve tips for creating online learning units for the health professions in low-and middle-income countries

Health professions educators in low-and middle-income countries are often sceptical about developing online learning units. This scepticism stems from the belief that online programmes are limited in developing clinical competence, and there are concerns about digital proficiency and resource availability. A social constructivist approach in designing online work-based learning units may overcome such scepticism. In this article, we use our experience in developing an online learning unit for healthcare education to suggest 12 tips for developing online learning units in a low-and middle-income context. The tips are nested in a 'promoting theory-practice integration framework' and include context, establishing communities of learning and practice, establishing foundational knowledge, practise in a work-based environment, and showcasing attainment of learning outcomes. By integrating the guidelines and framework, healthcare educators will be better equipped to develop online learning units and contribute to learning.

Comparison of peer-assisted learning with expert-led learning in medical school ultrasound education: a systematic review and meta-analysis

INTRODUCTION

Teaching point-of-care ultrasonography (PoCUS) to medical students is resource intensive. Peer-assisted learning, where the teacher can be a medical student, may be a feasible alternative to expert-led learning. The objective of this systematic review and meta-analysis was to compare the PoCUS performance assessments of medical students receiving peer-assisted vs expert-led learning.

METHODS

This study was submitted to PROSPERO (CRD42023383915) and reported with PRISMA guidelines. MEDLINE, Embase, ERIC, Education Source, Scopus, and Web of Science were searched from inception to November 2022. Inclusion criteria were studies comparing peer-assisted vs expert-led PoCUS teaching for undergraduate medical students. The primary outcome was performance assessment of PoCUS skills. Two reviewers independently screened citations and extracted data. The Cochrane risk-of-bias tool for randomized trials was used to assess study quality. Studies were included in the meta-analysis if mean performance assessment scores with standard deviations and sample sizes were available. A random-effects meta-analysis was conducted to estimate the accuracy score of practical knowledge test for each group. A meta-regression evaluated difference in mean scores.

RESULTS

The search yielded 2890 citations; 1417 unique citations remained after removing duplicates. Nine randomized-controlled studies conducted in Germany, USA, and Israel, with 593 participants, were included in the meta-analysis. The included studies assessed teaching of abdominal, cardiac, thoracic, musculoskeletal, and ocular PoCUS skills. Most studies had some risk-of-bias concerns. The estimate accuracy score after weighting is 0.56 (95% CI [0.47, 0.65]) for peer-assisted learning and 0.59 (95% CI [0.49, 0.69]) for expert-led learning. The regression coefficient estimate is 0.0281 (95% CI [- 0.1121, 0.1683]); P value is 0.69.

CONCLUSION

This meta-analysis found that peer-assisted learning was a reasonable alternative to expert-led learning for teaching PoCUS skills to medical students.
